During the Middle Ages and Renaissance, when Latin remained the dominant language in Europe for international educated discourse, mythological names almost always appeared in Latinized form. With the Greek revival of the 19th century, however, Greek names began to be used more often, and "Zeus" may be more familiar than "Jove" as the name of the supreme god of the classical pantheon.

During the Hellenization of Roman literature and culture, the Romans identified their own gods with those of the Greeks, adapting the stories told about them (see interpretatio graeca) and importing other myths for which they had no counterpart. For instance, while the Greek god Ares and the Italic god Mars are both war deities, the role of each in his society and its religious practices differed often strikingly; but in literature and Roman art, the Romans reinterpreted stories about Ares under the name of Mars. The literary collection of Greco-Roman myths with the greatest influence on later Western culture was the Metamorphoses of the Augustan poetOvid.

Syncretized versions form the classical tradition of mythography, and by the time of the influential Renaissance mythographer Natalis Comes, few if any distinctions were made between Greek and Roman myths. The myths as they appear in popular culture of the 20th and 21st centuries often have only a tangential relation to the stories as told in ancient Greek and Latin literature.
